First Blood (also known as Rambo: First Blood) is a 1982 action/thriller film directed by Ted Kotcheff. The film stars Sylvester Stallone as John Rambo, a troubled and misunderstood Vietnam War veteran, with Sheriff Will Teasle (Brian Dennehy) as his nemesis and Colonel Samuel Trautman (Richard Crenna) as his former commander and only ally. It was released on October 22, 1982. Based on David Morrell's 1972 novel of the same name, it was the first of the Rambo series. Unlike the sequels, which were war adventure films set in foreign countries, First Blood was a post-Vietnam War psychological thriller set in the United States. First Blood lacks the gore and violence that would become a trademark of the series.
